Question

explain in 20 linesabout colours of semi conductors​

Answer 1

Answer:

Colors of semiconductors :

The color of absorbed and emitted light both depend on the band gap of the semiconductor. Visible light covers the range of approximately 390-700 nm, or 1.8-3.1 eV. ... Similarly, CdS (Egap = 2.6 eV) is yellow because it absorbs blue and violet light.
